AND PROCESS FOR MAKING SAME.

Original Io. 1,458,776, dated It is among the objects of my invention to roduce a ball that may be easily and'cheapy manufactured, and which will resist hard usage and efiects of the elements. The ball is particularly adapated for use in the game i of base ball.

In the drawings, whichshow one manner of practicing the invention:

Figure 1 is a diagrammatic view of the material from which the body of-the ball is made;

Figure 2 is a partial sectional view of a conventional mold;

Figure 3 isa similar view with material in place for treatment;

Figure 4 is a perspective view of the ball after the first and partial curing;

Figure 5 is a plan of the'usual two-part ball cover; and

Figure 6 is a perspective view of the completed ball.

This ball is preferably made from stock for-tires andis ordinarily" composed of about equal aparts of rubber and fabric diagram matic ly illustrated in.Figure 1, the rubber being designated v1 and the fabric 2.

Thesematerials are reduced to a pulp-like inding mass in any suitable manner as by and moistening. The exact manner in which this pulp-like mass is prepared is immaterial so far as-my invention is concerned.

The materials 1 and 2 may be scrap or trimmings from tire stock which includes a high grade ofrubber and cotton fabric. 5 A conventional mold is shown in Figure 2 as comprising upper and lower plate members 3 and 4 with registering hemispherical cavities-5 therein. An excess of the pulpwlike material is placed in the molds 3, 4,

as indicated at 6 in Figure 3. The parts of the mold are pressed together and sub- {gcted to heat, which operation can readily performed in a vulcanizing ress. This first heating is carried far enoug to cement the pulp-like mass to ether and eifect a par-.

tial cure. The ball g then has the appearanceshown in Fi 4, the joining hne being evident but t e two parts being firmly held together.

As the next step, a cever is cut from pieces of tire material. This ma be cut in two pieces of the usual base b 1 cover form as June 12, 1923, Serial No. 528,610,111 January 12, reissue man 13, 1925. Serial No. 30,121,

base ball size and will be nearly the regulation weight.

It is very lively and will stand much more use than any baseball as at present manufactured.

What I claim is:

1. A baseball having a solid base and a {)ubberized fabric cover vulcanized to the ase.

2. A baseball comprising a solid base of rubber and fiber and a rubberized fabric cover. 7

3. A baseball approximating re lation size and weight comprising a mp1 ed base and a rubberized fabric cover vulcanized to the base.

4. A process of making a baseball which comprises molding a pulp-like mass including rubber and fiber to form a core of suitable size and weight, partially curing the mass in a mold, and then applying a rubberized fabric cover to the base and vulcanizing the assembly.

5. A process of making a ball which comprises preparing a pulp-like mass from trimmings of tire stock, subjecting a quantity of said mass to a partial cure in a spherical moldto form a ball, applying a twopreparing a pulp-like mass composed of substantially e ual parts of rubber and cotton fabric, su jectlng a quantity of said mass to a partial cure in a spherical mold to form a ball, applying a two-part cover of tire fabric to said ball, and subjecting it to a final cure in a mold, whereby the cover is intimately attached to said body.

A process of makini' a ball which comprises preparinia pulpe mass composed brie, subjecting aquantity a fabric containing rubber to the ball, and. subjecting it to a final cure in a, mold to 'vulcamze the cover to the body of the ball.

8. A ball comprising a body composed of of tire stock and a two-part the trimmin cover cured t ereto. I

9.' A ball comprising a body composed of trimmings of tire stock and a two-part cover of tire fabric vulcanized thereto.

10; A ball comprising a, body composed 15 of substantially equal parts of rubber and cotton fabric and" a two-part cover cured thereto.

In .witness whereof, I have hereunto signed my name.
